A certain sand-dune landscape is composed of two habitat types: semistabilized (SM) sand habitat and stabilized (ST) sand habitat. A researcher has observed that Gerbillus pyramidum (GP) mainly occurs in the SM habitat and G. allenbyi (GA) mainly occurs in the ST habitat. Axis of environmental heterogeneity is

a. Heterogeneity in food types
b. Heterogeneity in habitat types
c. Heterogeneity in environmental conditions in different parts of the night
d. Heterogeneity in disturbance regime
e. None of the above

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
